    Mitsubishi City Multi PARF27MEA mode flashing



    Hello

    Does anyone here know why the mode symbol (heating symbol in this case) would flash on a PARF27MEA, groups and units have been addressed properly.

    This is a standard 2 pipe I fitted back in 2010, 6 units in 6 groups on the system but three are flashing heat symbol and not running. Come on for a while and then stop. Ran for a while OK when I switched off and back on and re-addressed units.

    No Standby.

    No fault codes.

    Just flashing heat symbol and not running?

    Thanks

    Thanks!

    It's been running OK since 2009, it can only be an addressing issue. I re-addressed each unit to it's group but maybe there's other units still stuck in the memory!

    Does anyone know how to check that?

    Thanks

    Did you do a virgin restart?

    I guess it is a different operating mode. E.g. you set Heat mode while the non-recovery outdoor unit is in Cool mode
